# List of Atlantic subtropical cyclones

A subtropical cyclone is a cyclone with winds equivalent to a tropical storm, but without all the characteristics of a tropical cyclone. Such storms are usually weak, short-lived, form at mid-latitudes, and rarely affect land.
In the Atlantic Ocean, subtropical storms often form, with an average rate of one per few seasons. Since they started being tracked in the 1960s, there have been 31 of them. Subtropical storms started being named as a part of the regular season in 2002, though they were briefly given names from a different list in the 1970s.
This list does not include any subtropical cyclones that became tropical storms or hurricanes.
